Claims.

` My invention relates to aerials, and has among itsf objects and advantages the provision of an improvedaerial mounting.

kthe embodiment selected to illustrate my invention; yIrmake `use of four grip members I8 grouped inl pairs and pivotally connected together through the medium of bolts I2. These bolts are screwed into threaded openings in the ends of a bar I4, see Fig. 2. In Fig. 1, I illustrate the grip membersA as being bent forA arranging the ends I6 in each pair to lgrip opposite sides of the coping I8. I prefer to makethe ends pointed so that rm anchorage is attained in connection with brick or stone walls.V

In Fig. 2, the grip members I0 in each pair are spaced apart to receive the flattened end of a threaded tube 22. v An opening is provided in the flattened part 28 to receive its respective bolt I2. "Upon each tube 22, I mount a clamp member 24 having an opening to loosely receive its respective tube 22. 'I'his clamp member is bent to provide flange parts 26 having their ends arranged in contact with the grip members Iii, see Fig. l.

Means for forcing the clamp members 24 into clamping relation with their respective grip mem- 4o bers I0 comprises a sleeve 28 mounted upon each of the tubes 22 and having threaded relation therewith. When this sleeve is screwed down, its lower end engages its associated clamp member 24 and causes a pivotal action of the grip 45 members Ill about the axis of the bolt I2 so that the ends I6 will grip the coping I8 for holding the aerial structure in rm assembly with the coping. I prefer to provide a tapered area 30 as a part of the opening in the clamp members 24 50 for receiving the tapered end of the sleeve 28. A lock nut 32 may be mounted upon each of the tubes 22 for fastening the sleeves 28 in position.

My aerial mast 34 comprises a tube having a threaded end 36 connected in axial alignment with 55 one of the tubes 22 through the medium of a union 38. In Fig. 2, the mast 34 has its upper end threaded to receive a nutv and a cap Q2 between which the loop end of a wire d is con-rv nected. This wire carries an insulator 45 connected with the aerial 48', which in turn in connectedwith the lead in wire 5U. YOi course, two mast mounting units are employed for the aerial 48. However, three units will accommodate two aerials. To thisend, a second mast 34 maybe connected with the tube 22 having the cap 52, see Fig. 2. In this way, two mast units, each havingv one mast 34, may be associated with one unit having two masts to accommodate the two aerial arrangement with three mast mounting units.

However, two units will accommodate two aerials in cases where the units are mounted upon opposite sides of the building. This arrangement is advisable in cases where the width ofthe building is sufficient to accommodate an aerial of proper length. Theloose connection between the loopparts of the'wire 44 and the-mast permits the aerial to be arranged in various alignments. To make a sturdy construction, I arrange two bars'54 and 56 between each pair of grip members I Il grouped for clamping opposite sides of the coping I8. These bars are provided with threaded openings for the reception of fastening screws 58. An arm 6I) is fastened to one of the grip members IU for supporting the lead in wire 50 in spaced relation with the coping and the wall part of the building structure. This arm is provided with a plurality of insulated openings 62 for the reception of one or more lead in wires. Referring to Fig. 5, the arm is provided with an opening for the reception of one of the screws 58 and is provided with a pin 64 projecting through an opening in the grip member I0 to which the arm is connected. In this way, the arm is clamped in firm assembly with the grip member when its respective screw 58 is turned down.

When the sleeve 28 is screwed down tightly against its respective clamp member 24, all the movable parts ofthe unit at that end will be clamped into a rigid assembly. The clamp member 24 operates to align the tube part 22 in a vertical position, so that Vthe tube 22 will always bisect the angle between the grip members I0.

In certain cases it may be desirable to protect the coping I8 from the points I6 of the grip members. To this end, I pivotally connect a plank 66 with the ends of the grip members 68 through the medium of brackets lll. This planking may be provided with a plurality of small lugs 'I2 arranged to be imbedded in the coping wall when the members 68 are clamped in position. Obviously,

an individual pad for the end of each of the clamp members B8 may be pvotally connected therewith in lieu of the plank 66.

The foregoing will so fully explain my invention that others may, by applying current knowledge, readily adapt the same for use under various conditions of service.

I claim:

1. An aerial mast mounting comprising two pairs of grip members shaped to pass over the coping of a wall structure, a bar arranged to hold said pairs of grip members in spaced apart rela-k u tion, a bolt for pivotally connecting each pair with .one end of said bar, the grip members in each pair being spaced apart, a vertical member arranged between the gripmembers ineach pair` and pivotally connected with the boltassociated with that pair, a clamp member loosely connected with each vertical member for moving the grip members into clamping relation with the coping, means co-operating with each vertical member to force its respective clamp member into clamping relation with the grip members, and a mast connected with one of said vertical members.

2, An aerial mast mounting comprising two pairs of grip members shaped to pass over the coping of. a wall structure, a bar arranged to hold said pairs of grip members in spacedapart-.relation, a bolt for pivotally connecting each pair with one end of said bar, the grip members in each pair being spaced apart, a vertical member Varranged between the grip members in each pair and pivotally connected with the bolt-associated with that pair, a clamp member loosely connected with each vertical member for moving the grip members into clamping relation with the coping, means co-operating with each vertical member to force its respective clamp member into clamping relation with the grip members, and bar means for interconnecting the grip members,.and a mast connected with one of said verticalrmembers.

3. In a mast mounting, two pairs of grip members, the members in each pair beingpivotally connected together with the other grip member in that pair, means for operatively connecting the two pairs of grip members :in spaced relation, a vertical extension loosely connected with the pivotal connection between the grip members in each pair, and means associated with said vertical extensions and said pairs of grip members, to clamp the vertical extensions and the grip members into a rigid assembly upon a supporting structure.
